CODE NAME
Speeds error (Gear ratio in reverse, 1st, 2nd, 3rd, 4th)
CODE DESCRIPTION
Code 50 - 54 sets if the ratio of the input RPM to the output RPM does not compare to a particular gear ratio.
A hard fault is considered to exist when the fault counter has matured to a value of 225. An intermittent fault is considered present when the fault counter is greater than or equal to 6 and less than 255.
No fault is considered to exist when the fault counter is less than 6.
PROBABLE CAUSE
- Malfunction of input speed sensor
- Malfunction of output speed sensor
- Hamess or connector between input speed sensor and TCM open or short-circuited
- Harness or connector between output speed sensor and TCM open or short-circuited
- Malfunction of TCM
- Internal transaxle problem
